BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoa plant, botanically known as Calibrachoa sp. and hereinafterreferred to by the name ‘Duecalhulpapi’.

The new Calibrachoa plant is a product of a planned breeding programconducted by the Inventor in Rheinberg, Germany. The objective of thebreeding program is to create new uniform Calibrachoa plants with largeand uniquely attractive flowers.

The new Calibrachoa plant originated from a cross-pollination made bythe Inventor in July, 2013 in Rheinberg, Germany of a proprietaryselection of Calibrachoa sp. identified as code number AA12-003572-002,not patented, as the female, or seed, parent with a proprietaryselection of Calibrachoa sp. identified as code number AA12-002131-002,not patented, as the male, or pollen, parent. The new Calibrachoa plantwas discovered and selected by the Inventor as a single flowering plantfrom within the progeny of the stated cross-pollination in a controlledgreenhouse environment in Rheinberg, Germany in May, 2015.

Asexual reproduction of the new Calibrachoa plant by vegetative terminalcuttings in a controlled greenhouse environment in Rheinberg, Germanysince July, 2015 has shown that the unique features of this newCalibrachoa plant are stable and reproduced true to type in successivegenerations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Duecalhulpapi’. These characteristicsin combination distinguish ‘Duecalhulpapi’ as a new and distinctCalibrachoa plant:

-   -   1. Outwardly spreading to trailing and decumbent plant habit.    -   2. Vigorous growth habit.    -   3. Freely branching habit.    -   4. Early and freely flowering habit.    -   5. Large pink and red purple bi-colored flowers.    -   6. Good garden performance.

The new Calibrachoa can be compared to plants of the female parentselection. Plants of the new Calibrachoa differ primarily from plants ofthe female parent selection in flower color as plants of the femaleparent selection have pink-colored flowers. In addition, plants of thenew Calibrachoa flower earlier than plants of the female parentselection.

The new Calibrachoa can be compared to plants of the male parentselection. Plants of the new Calibrachoa differ primarily from plants ofthe male parent selection in flower color as plants of the male parentselection have dark pink-colored flowers. In addition, plants of the newCalibrachoa are more vigorous than plants of the male parent selection.

The new Calibrachoa can be compared to plants of Calibrachoa sp.‘Duecalhulapp’, disclosed in a U.S. Plant patent application filedconcurrently. Plants of the new Calibrachoa differ primarily from plantsof ‘Duecalhulapp’ in flower color as plants of ‘Duecalhulapp’ havelighter pink-colored flowers. In addition, plants of the new Calibrachoahave thicker lateral branches and longer leaves than plants of‘Duecalhulapp’.

Plants of the new Calibrachoa can also be compared to plants ofCalibrachoa sp. ‘Duealroywi’, not patented. In side-by-side comparisons,plants of the new Calibrachoa differ primarily from plants of‘Duealroywi’ in the following characteristics:

-   -   1. Plants of the new Calibrachoa have narrower leaves than        plants of ‘Duealroywi’.    -   2. Plants of the new Calibrachoa are more freely flowering than        plants of ‘Duealroywi’.    -   3. Plants of the new Calibrachoa and ‘Duealroywi’ differ in        flower color as plants of ‘Duealroywi’ have white-colored        flowers with purple violet-colored venation.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurementsand values describe plants grown during the summer in 12-cm containersin a glass-covered greenhouse in Rheinberg, Germany and under culturalpractices typical of commercial Calibrachoa production. During theproduction of the plants, day and night temperatures averaged 18° C. andlight levels averaged 4,500 lux. Rooted young plants were pinched onetime three weeks after planting and were 13 weeks old when thephotographs and description were taken.
